--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The current disposition of the Library Working Group is to leave it that way,
because it doesn't meet the traditional iterator requirements, so it's expected
that iterator_traits is empty for it.
As you already know, you can use range_value_t<decltype(view)> to get the value
type instead, and range_difference_t for the difference type, and use the
concepts std::input_iterator, std::forward_iterator etc. to determine which
concepts it satisfies. Code written to work with ranges should rely on those
interfaces, not iterator_traits, which is for traditional iterator types.
